' To all whom it 'majaoncern:

Beit known that'l, J o'sEPH MORTON, a citizen of the United States, residing at Lindon, countyof Utah, and State of Utah, have in vented certain new and useful Improvements in Sliding-JawWrenches, of which the'following is a specification.

-user, so that the sliding jaw can be readily.

adjusted to approximately the-desired position andrthereafter" a fine adjustment {obtained by turning the screw'into engagement With-thethreads on-the sliding jaw.

'- Another object 'of the invention is 'th pro- .visionrof a wrench ofthe-type set forthwhich' will be composed ofjfew parts, durable,

strong", and not liable to-become damaged or get-out of order,

. Incarrying out the invention, I provide the balance being blank, andlinoonnecti ontherewith employ an. adjusting I screw which has interrupted screw threads to engage those on the sliding jaw, 'but these screw threads are of lesswidth than the open. side in the sliding 'aw so-that by turningthe -adju;sting-screw to ring the interrupted screw threads thereof inalinement with the open'side in the sliding jaw, the s'li ding jawfcan he quickly-slid to fuponreengagement of the adjusting'screw with thethreads on the sliding aw, a fine adjustment of the slidingjaw 'may be quickly obtained.

part thereof it is rovi'de gage with a lugon the wrench-and-its construction issuch that it may be readily'removed at any time. p I

In the accompanying drawings: Figure 1 1s a side-elevation with a part of the wrench in section; Fig 2, an edge View; partly in section; Fig. 3, a cross-section .online 33 of Fig. 1, but showing the adjusting screwturned so that the interrupted screw; threads" .6 5 I thereon are in aline'ment with the open side in the sliding jaw; and Fig. 4,- a detail erspective'of the sliding jaw with parts bro 'en away to" better illustrate the interrupted screw threads. v f

To the usual'handle lis secured the guide bar. 2., which hasthe fixed-jaw 3. Attached The slidin jaw is shown at .6, the same having. a soc e't'7 which is cylindrical and perfectly smooth, except at one side where is provided withinterru ted and depressedscrew-threads 8. The sli 'ng jaw hasan 0 en side 9 which communicates with the soc et The adjusting screw 10 has a screw'threader led part 11 to en age the screw threads'fiaand its stemj12 isof ess diameter than the screw to the guide-bar 2, is'an arm or lug 4 which "has internal screw threads at 5.

threaded opening 5' and perfectlysmooth and 5 cylindrical throughout its len th and of a size to fitthesocket 7, .exce t t atalongone with the-interrupted'screw-threa .s, .13 corresponding-to the screw-threaded part 8. Theyscrew-threads turned with the fin ers to bring the threads :13 into the open side-9 and the sliding jaw'fi isthen slid along to the desired positionand thereafter the adj usting'screw is" turnedto cause v the screw threa 13 to engage the screw threads '8 and a fine adjustment of the sliding jaw can then be obtained. I

c On account of the stem of the adjusting screw being of less size than the screwthreaded o ening 5', the adjusting'sorew can be remove through the opening. 5 when desired.

'l-he screwthreads 13, in connection with means by which the user can, without caretulobservation, at once position the parts so .13 are, as shown in Fig. 3, of less width than v the o' enside 9 so that when the screw is 1 turne to bring the threads 13 into the open side, the'sl-iding jaw can-be freely slid along .theguide-b'ar 2. j i Y operation, the thumb p ece 10* is the open side 9; constitute an indicating I10 that the sliding 3m maybe rapidly slid on, the guide-bar, and this construction also ob-- .viates the" necessity of using limiting or stop lugs of any kind on the adjusting screw.

Having" thus described my invention, What, I claim as new and desire to secure by Let ters Patent, is I 1. In a wrench, the combination with a 'guide bar of a sliding jaw having a socket provided ivith interrupted screw-threads and with an open side extending lengthwise of the sliding jaw and guidebar, and an adjusting screw received in the socket and provided with interrupted screw-threads adapted to be brought into alinement with the aforesaid o n side or engaged with the screw threads -o the sliding jaw.

2. In a wrench, the combination with a guide-bar and an arm or lu having a screwthreaded opening, of a slirfing jaw movable I sas es signature in presence of two witnesses;
